Description
A & B Developer Powders are paired bottles of pre-measured, pre-weighed dry ingredients that are dissolved in tap water to make fresh developer solution for Ulano gelatin-based (iron salt sensitized) indirect system, photographic stencil films.
A & B Developer Powders are pre-measured for mixing pints, quarts, or gallons of developer solution. As a user of Ulano Indirect System Photographic Films, A & B Developer Powders remain your best assurance that the developing step will be a constant in your stencil processing.
Because A & B Developer bottles are tightly sealed, the contents will not degenerate in storage (unlike hydrogen peroxide). This assures absolute freshness and proper concentration of the developer solution. A & B Developer Powders contain special buffers that minimize the effect of mineral content in your water. Pre-weighed, pre-mixed, fresh-until-opened A & B Developing Powders effectively eliminate any variables in the developing step when you process indirect system gelatin-based films.
